As others have said it is pricey. However, I absolutely love mine. If you can buy it at the outlet or catch it on sale at the end of the season that is the way to go. I have their cold weather gear and early season gear. Wouldn't have it any other way.
Take a look at the UA label to see what the material is made of. As far as I know, they aren't using some proprietary material that the competitition can't duplicate.
I wanted the ridge reaper light gear for bow hunting here in Mi for the fall. I tried on the coat and seemed to stiff for me. I love the mask and gloves though.
